FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to traumatology and ortghopedics, and is intended for treatment of fractures of long tubular bones. Apparatus contains supports, threaded bars, connecting supports, intraosseous rods, rod-fixers and remote rod-fixers on form of beam. Supports are made in form of arch-like plates, curved on radius in their plane, and bent in said plane in form of projections from terminal parts of plate toward its salience. Projections and terminal parts of plate are provided with holes with bilateral countersink. Holes, located on radius, are made along plate. Beam of remote rod-fixer is immovably fixed on cylindrical pedestal, which has axial threaded hole and is installed on base in form of washer, on the centre of lower surface of which placed is square boss with axial through hole. Base is installed on base with boss in hole, located on radius along plate. On the upper surface of base made are radial teeth, which contact with teeth of respective shape on the lower surface of pedestal. Pedestal and base are connected with support by means of screw connection. On wide sides of rod-fixer beam made are transverse teeth, along axis of said sides made is through oval slot for installation of intraosseous threaded rods, fixation of which in remote rod-fixer is performed by means of special nuts and washers. Nut has spherical head and hexagonal shank, which are connected to each other by means of tube. Washer is made rectangular and is provided with longitudinal oval slot for intraosseous rod. In the centre of slot made is depression of respective shape for head of spherical nut. On the end of upper surface, along short side of said washer, made is step, on the opposite end of lower surface, for the half of washer height - depression in the centre, for the width of central slot. On the lower surface of washer made are transverse teeth, in shape corresponding to teeth on lateral surfaces of remote bracket.EFFECT: invention ensures increase of fixation rigidity, reduction of operation treatment trauma with improvement of its outcome and creation of comfort for patient.3 dwg |
